installer zfs datasets

[Heikki Lindholm]

Hi,

In the 10.3 installer, doing auto zfs install creates a bunch of 
datasets on rootfs, however, if I select to do my own partitioning (and 
proceed to do that in the shell) and then select to have zfsroot on the 
partition allocated for root, it only creates a single dataset for root. 
Can I somehow mimic the auto mode of the installer and still do my own 
partitioning?

I basically only want an additional EFI partition and control the sector 
alignment of the other partitions. I can probably look at source code of 
the installer and do what it does manually, but if there's a better way..
